Using the TOSNA calculator https://www.meadmakr.com/batch-buildr/
it outputs the following sequencing instructions, which seems backward to me:
It sequences Fermaid-O first, then later Fermaid K and DAP. But Fermaid K is supposed to have micronutrients, so shouldn't it go first? Also, I've read that 1. DAP promotes yeast cell reproduction more than Fermaid-O does and 2. as specific gravity drops, the yeast cells eventually can no longer process DAP but can still process Fermaid-O. So, therefore, wouldn't it make more sense to sequence Fermaid-O last?

Fermaid K / Fermaid O / DAP Nutrient Protocol
The total amount of Fermaid O, Fermaid K, and DAP that will be added to your must are 1.7g, 1.9g, and 3.4g, respectively. The nutrients will be divided into 4 staggered nutrient additions. To avoid mead eruption accidents, degas must and dissolve yeast nutrient doses in 1 cup must prior to adding to the fermenter.
At 24 and 48 hours after you pitch your yeast, add 0.85g Fermaid O to your must.
At 72 hours after you pitch your yeast, add 0.95g Fermaid K and 1.7g DAP to your must.
When the must reaches the 1/3 sugar break (1/3 of all available sugars are consumed, i.e. 1.120 starting gravity reaches 1.080 or 21 Brix reaches 14 Brix), but no later than 7 days after yeast pitch, add the last dose of 0.95g of Fermaid K and 1.7g of DAP.
If mead starts to show signs of yeast stress from low nutrients after last nutrient dose (evidenced by sulfur smells), add 0.85g Fermaid O as needed to supplement for a high nutrient requirement yeast.
